通常，全局变量被作为一个参数传递给立即执行参数，这样它在函数内部不使用window也可以被访问到。
multiprocess and distributed data collectors(2) that work synchronously or asynchronously. Through the use of TensorDict, TorchRL's training loops are made very similar to regular training loops in supervised learning (although the "dataloader" -- read data collector -- is modified on-the-fly):...
进程(multiprocessin模块中Process创建,进程池:Pool):正在运行的代码。是操作系统进行资源分配和调度的基本单位,每个进程都独享系统的一部分资源,进程间的资源不共享,各进程间的变量是相互独立的。进程间通信方式:消息,队列,信号量,一个进程可以包含多个线程,同一个进程中的不同线程共享该进程的环境资源。
